R B R R B B R R R B B B R R R R B B B B Alternated Marble Stacking

Attempt to make a track that when you release a RED marble the pattern that follows is RBRRBBRRRBBBRRRRBBBB (11223344) I was only able to get to 3 of each and I tried for hours. I’m curious what everyone else will think.

Good Luck
